Description
Technical field
The present invention relates to a kind of warn device that is used for well lid.
Background technology
Usually, the well lid plate of various well heads is directly should be on the walling crib seat on the road, and it is stolen that the well lid plate often takes place, and perhaps causes that the well lid plate is damaged because vehicle rolls, even flies away from the walling crib seat, causes well head to lack lid, seriously influences pedestrian and vehicle safety.Current; There are a lot of innovation and creation to address this problem through installing syndeton additional, install locking device additional or reinforcing variety of way such as well lid plate; For example patent of invention " Manhole cover assembly " (application number 02149417.7) provides the Manhole cover assembly that a kind of well lid plate and walling crib seat are connected as a single entity with a kind of permanent ways of connecting; Patent application " the built-in lockset well lid of multilayer protection " (application number 201010580756.X) provides a kind of built-in lockset well lid of multilayer protection that can realize the multilayer protection; Patent application " ring bar type manhole cover " (application number is 201010125737.8) provides a kind of ring bar type manhole cover that is made up of lid, cycle beam, dowel, radial rib and interior collar tie beam; Improved the anti-pressure ability of inspection shaft lid; But owing to receive effects limit such as cost, this problem is not still solved preferably, and pedestrian or vehicle are because well head lacks the security incident that lid causes takes place repeatedly.Therefore, when the well lid plate is lost or be damaged, how can remind pedestrian and vehicle timely, just become the problem of necessary solution.Patent application " intelligent anti-theft loss prevention report to the police outdoor well lid and alert management system " (application number is 201010594660.9) discloses a kind of intelligent anti-theft loss prevention report to the police outdoor well lid and alert management system; The intelligent anti-theft loss prevention that aim to provide a kind of intellectuality, has a good antitheft loss prevention warning performance report to the police outdoor well lid and alert management system; Patent application " safety type solar LED Sewage well cover report to the police automatically indication device " (application number is 201010283178.3) has proposed a kind of safety type solar LED Sewage well cover indication device of reporting to the police automatically; Can in time carry out alarm when abnormal conditions such as breakage or displacement appear in well instantly to pedestrian or vehicle; But the foregoing invention creation need be installed various electronic equipments or circuit under the well lid plate, and for the subsurface environment that often is in hot and humid mal-condition such as grade, the reliability of equipment can not get ensureing; Be very easy to ageing failure; Simultaneously, if at various well heads said apparatus is installed all, cost is very high.
Summary of the invention
In order to overcome the deficiency that prior art is with high costs and reliability is lower, the present invention provides a kind of well lid automatic alarming device, prompting pedestrian and vehicle that can be in time eye-catching, and simple in structure, with low cost, reliability is high.
The technical solution adopted for the present invention to solve the technical problems is: comprise warn rod and spring, the rod of warning is the column of surface-coated reflectorized material, is connected in the walling crib seat through spring; Warn rod perpendicular to the well lid board plane, and the rod of warning at ordinary times is crushed under the well lid plate, and spring is in compression or extended state; When the well lid plate is lost or is damaged; The rod of warning stretches out the walling crib seat under spring action, play tangible warning function with its gay colours by day, under the situation of night or insufficient light; Its bright reflecting effect can strengthen people's recognition capability effectively, sees target clearly.
Described warn the rod and spring be installed in plastics or the rubber cylinder; Cylinder is fixed in the walling crib seat; Lower end closed, upper end are through the plastic sheeting sealing, and guarantee to warn rod and spring are in for a long time, and aging or corrosion can not take place under the high humidity environment yet; And can not cover through the dust dirt that the well lid plate falls yet and to pollute the rod of warning, the display degree of rod thereby influence is warned.When the well lid plate was lost or be damaged, the rod of warning was at first poked the plastic sheeting of cylinder upper end under spring action, stretch out the walling crib seat then, reminds pedestrian and vehicle.
The described rod of warning has several, is evenly distributed in the walling crib seat along circumference, and when the well lid plate had only part damaged, the rod of warning at this place will stretch out the walling crib seat under spring action, reminded pedestrian and vehicle.
Also be coated with self-luminescent material on the described rod of warning, when not having bright source night, can remind the pedestrian.
The invention has the beneficial effects as follows: the present invention is simple in structure, only comprises warn rod and spring, accomplishes goal of the invention through the simplest frame for movement, need not electronic equipment or lays circuit in the down-hole, and reliability is high.In addition, the present invention adopts the rod of warning to stretch out the outer scheme of well and warns, and visibility is high, causes pedestrian and driver's attention easily, and effect is more obvious.
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
